I rechecked and found out that I didn't use fpga_bridge3. I disabled and regenerate the DTB but the error still happened. The error looks like the fpga_manager cannot find my rbf, no? Am I putting it at the correct place, which is "/lib/firmware"?
I'm interested in how this works as well. Did you have to do anything with udev rules?
Mine contains: cat /lib/udev/rules.d/50-firmware.rules # do not edit this file, it will be overwritten on update SUBSYSTEM=="firmware", ACTION=="add", RUN{builtin}="firmware"
Another question, do I configure the DTS correctly, especially the reg and ranges. I attached along my working DTS which I used in kernel 3.10.

But after I execute "echo socfpga_gen3cam_fpga.dtbo > /config/device-tree/overlays/socwks/path", I get error "fpga_manager fpga0: Error requesting firmware cyclonev_bw.rbf". FYI, I have put cyclonev_bw.rbf in /ib/firmware. Any idea guys? I attached along my DTS.
